I bought a handheld calculator more than 10 years ago. But recently they moved to a subscription that I think is way over-priced. I also believe it’s behind the times for these reasons: 1. You can only see one number at a time, you cannot easily see what you’ve previously entered. 2. The History Tape is very hard to use, so unintuitive. 3. Cannot calculate things as simple as parentheses. 4. Saving numbers using M+ and Memory Registers is such an old-school way to do things. Phones are so much better than that. 5. With this, I decided to make my own app that’s meant to be much more intuitive. Please try my app, SteelSolve, free version is completely functional with no ads! ### 4/5 — Great tool *2026-07-16, version 12.11.12* Great tool just a little pricey. Helps get ya started for sure but just go by one when you get the $$ ### 5/5 — 👌👌 *2026-06-25, version 12.11.11* The best calculate in the world ### 5/5 — Great app *2026-06-24, version 12.11.11* I have had a construction master pro for a long time. Having it on my phone is so incredibly convenient!! ### 3/5 — Comprar *2026-06-21, version 12.11.11* Yo ya la tenía comprada en Android porque no se me pasó para el iPhone si es el mismo correo? ### 5/5 — Overpriced *2026-06-17, version 12.11.11* Great app but not worth $30 a year ### 5/5 — Carpentry/ Trades *2026-06-07, version 12.11.10* I have used this calculator since 1999. I taught it for nine years at Salt Lake community college and UVSC. I love it. ### 5/5 — Recommend *2026-06-05, version 12.11.10* Jala al 100 ### 5/5 — Wonderful construction Calculator *2026-06-03, version 12.11.7* Accurate construction Calculator ### 5/5 — Buena *2026-06-02, version 12.11.7* Buena application ### 5/5 — The Best Tool *2026-06-02, version 12.11.7* Excellent !!!!! ### 5/5 — Best construction Calc out there!! *2026-05-20, version 12.11.7* I’ve been using this app for over 10 years, probably closer to 15. I’ve tried other apps and nothing compares. I’ve had buddies recommend apps and once I showed them mine they used mine every time. ### 5/5 — Best construction tool on my pocket *2026-05-12, version 12.11.6* I’ve used this steadily for 15 years, whether the physical version or the phone version ## Most critical reviews (10 lowest-rated) ### 1/5 — $40 a year for a calculator? *2026-08-20, version 12.11.18* This is a trash download when there are many other apps for FREE. What got me was they didn’t spring this fee up till after download. Just be upfront and charge it for download, not a subscription. I’d give it zero stars if I could ### 1/5 — subscription based trash *2026-07-10, version 12.11.12* I hate downloading apps just to be met with a pay window to use anything. I would rather pay once than monthly for a calculator… ### 1/5 — HAVE TO PAY TO USE *2026-06-21, version 12.11.11* Free to download but won’t let you use anything until you buy a monthly subscription ### 1/5 — Subscription calculator!? *2026-06-12, version 12.11.10* The 5 star reviews have got to be fake accounts! There’s no way people are happily paying yearly subscriptions for a construction calculator app. Great product being taken over by greedy business practices. You don’t even deserve the 1 star I had to give you to post this! ### 1/5 — Ridiculous *2026-06-08, version 12.11.10* Pay monthly for a calculator. I hate this subscription based world we’re forced into. ### 1/5 — Bad Business *2026-05-16, version 12.11.7* Used to be able to purchase this app for $25 and have it for as long as you want on that account. I switched from android to iphone a couple years ago and found out it is now subscription based AND they wouldn’t honor my old purchase. Just another scummy business moving to subscription services to gouge your hard earned money. ### 1/5 — Bunk *2026-05-13, version 12.11.6* For real this is what’s wrong with apps…and capitalism, a subscription for a calculator? Seriously bunk. Didn’t really even get to use the calculator before being bombarded with adds and subscriptions and up charges. Bunk. Who are the malicious maniacs behind this? Bunked-up War pigs. I just want a construction calculator, leave me alone techno-fascist. ### 1/5 — Required Subscription *2026-03-12, version 12.10.31* Can’t use unless you subscribe to their subscription ### 1/5 — Sad *2026-03-09, version 12.10.31* Subscription service! Pretty sad that you have to pay monthly. Old phone I just paid once. ### 1/5 — Overpriced calculator *2026-02-20, version 12.10.24* Basic functionality, nothing to wrote home about. Terrible value for money, it's on a subscription service ## Most praised reviews (10 highest-rated) ### 5/5 — Best out there *2026-08-23, version 12.11.18* Once you use it. You’re hooked ### 5/5 — AWESOME CALCULATOR *2026-08-22, version 12.11.18* Very Handy Works Great for all types of Calculations ### 5/5 — The best *2026-08-10, version 12.11.18* The best, super helpful ### 5/5 — Super tool *2026-08-10, version 12.11.18* Super tool ### 5/5 — The best Construction calculator there is without a doubt *2026-08-03, version 12.11.16* Construction master was one of the first ones out, and it still remains to be in my opinion The best there is ### 5/5 — I *2026-07-15, version 12.11.12* Works great ### 5/5 — Excellent *2026-07-08, version 12.11.12* Been using for 20 years now great calculator ### 5/5 — Framer/Electrician *2026-07-05, version 12.11.12* I have loved the Constriction Master since they were introduced. Before cellphones you would find one in my bags at all times. ### 5/5 — Buena *2026-07-04, version 12.11.12* Excelente, no tengo por 13 años y muy buena aplicación. La pagué sólo una vez ### 5/5 — Best purchase for carpenter *2026-06-30, version 12.11.12* How I lived without this is unreal --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
